[0002] The circuit board is an important electronic component, a support for electronic components, and a provider of electrical connections for electronic components. Because it is made using electronic printing technology, it is also called a printed circuit board.

[0003] At present, during the production process of circuit boards, they need to be packed in boxes after testing. In order to improve the safety and protection of the circuit boards in the packaging box, foam pads need to be added. On the traditional assembly line, the circuit boards are adsorbed and loaded into the foam according to the process, and the foam is adsorbed and transported to the packaging box again. At least 2 manipulators and multiple circulation lines need to be set up on the assembly line. The overall linear assembly line is adopted, the station layout is long, and the transfer rhythm between each station is slow. Therefore, an automated equipment with compact circulation and efficient assembly is needed. Summary of the invention

[0004] The purpose of the present invention is to solve the above technical problems and provide a circuit board packaging automation equipment and its assembly line connection method, so as to achieve a compact transfer rhythm of circuit boards, foams, and packaging boxes, efficient circuit board packaging, and high assembly line transportation efficiency. In order to achieve the above purpose, the technical solution of the present invention is as follows:

[0006] A circuit board packaging line connection method comprises the following steps:

[0007] The circuit board is positioned in a carrier, and the carrier is transferred to a carrier circulation line;

[0008] The carrier circulation line drives the carrier to move to the position of the code reader, the code reader reads the two-dimensional code data on the circuit board, and the manipulator selects the corresponding first gripper to pick up the circuit board;

[0009] The foam material distribution conveyor line conveys the foam to a designated position, and the first gripper places the circuit board in the foam for positioning;

[0010] The packaging box circulation line conveys the packaging boxes to the designated location, and the cover plate storage device conveys the cover plates to the designated location;

[0011] The manipulator quickly switches to the second gripper, and the second gripper transfers the foam in the foam material distribution conveyor line to the packaging box in the transfer conveyor line. The second gripper transfers the foam loaded into the circuit board multiple times until the packaging box is filled;

[0012] The manipulator quickly switches to the first gripper again, and the first gripper moves the cover plate in the cover plate storage device and positions it to the packaging box in the transfer conveyor line, and the cover plate covers the packaging box to realize the packaging and capping of the foam;

[0013] The labeling machine prints labels based on the circuit board information identified by the barcode reader and sticks the labels to the outside of the packaging box on the transfer conveyor line;

[0014] The transfer conveyor line transfers the packaging boxes to be unloaded from the box delivery conveyor line.

[0015] Compared with the prior art, the beneficial effects of the circuit board packaging automation equipment and the assembly line connection method of the present invention are mainly reflected in:

[0016] The carrier circulates along the carrier circulation line for loading. During the circulation of the carrier, the carrier can be lifted close to the code reader to read the code and identify the circuit board information. The code reading operation can be completed during the movement of the carrier, and the code reading step and the carrier unloading step can be performed simultaneously; the manipulator has a quick-change function, and the first gripper or the second gripper can be replaced according to the needs of use. A single manipulator can complete the circuit board transfer, foam transfer, and cover plate transfer actions.

The automation equipment in this embodiment changes the traditional linear assembly line method, and multiple circulation lines are uniformly arranged on the same working platform, with a compact structure, and a single manipulator 5 realizes the handling coordination of multiple circulation lines.

[0032] The carrier circulation line 1 includes a carrier slide rail 11 and a bearing module that is movable along the carrier slide rail 11; the carrier slide rail 11 is arranged along the Y-axis direction of the working platform, and the bearing module includes a bearing plate 12, a group of driven synchronously circulating bearing belt lines 13 arranged on the bearing plate 12, and a base plate 14 that is arranged to be lifted and lowered on the bearing plate 12. A group of bearing belt lines 13 are arranged vertically relative to the carrier slide rail 11, and a group of bearing belt lines 13 are arranged along the X-axis direction of the working platform. Baffles 64 for limiting the carrier 63 are arranged on both sides of the bearing belt lines 13, and the carrier 63 can be stably positioned in the bearing belt lines 13 under the limitation of the baffles 64. The top of the base plate 14 supports the carrier 63, and a cylinder for limiting the carrier 63 is arranged at the end of the bearing plate 12 on the working platform. The carrier 63 is raised when needed and lowered when not needed. A number of guide pillars and guide sleeves are arranged between the base plate 14 and the bearing plate 12, and a cylinder for driving the base plate 14 to rise and fall is arranged on the bearing plate 12. The bottom of the bearing module is connected to a motor and a belt line assembly that drives it to move along the carrier slide rail 11.

[0033] The carrier 63 is a double-layer spacing structure, and a positioning groove 65 is provided in the carrier 63 to match the circuit board 6. Both sides of the positioning groove 65 are provided with hand-picking grooves 66, so that the robot 5 drives the first gripper 51 to grab and transfer. Since the carrier 63 is a double-layer spacing structure, it does not interfere with the components on the circuit board 6, so that the circuit board 6 has a certain spatial height for positioning.

[0034] The carrier circulation line 1 also includes a carrier unloading conveyor line 15 arranged on the side of the carrier slide rail 11. When the carrier is unloading, the carrying module is aligned with the carrier unloading conveyor line 15, and the carrying belt line 13 circulates and drives the carrier 63 to move along it. The idle carrier 63 moves and transitions to the carrier unloading conveyor line 15 for unloading.

[0035] A gripper rack 53 for storing the first gripper 51 and the second gripper 52 is arranged above the carrier slide rail 11, and a group of placement racks for positioning the first gripper 51 and the second gripper 52 are arranged on the gripper rack 53. The placement rack includes a plurality of placement columns 54 and electromagnets 55 arranged on the placement columns 54; placement holes corresponding to the placement columns 54 are arranged in the first gripper 51 or the second gripper 52, a group of electromagnets 55 respectively position the bottom of the first gripper 51 and the second gripper 52, and a proximity switch for sensing the first gripper 51 or the second gripper 52 is arranged on the side of the placement column 54. When the first gripper 51 or the second gripper 52 is positioned on the placement rack, the proximity switch senses that it is in place, and the electromagnet 55 is adsorbed and positioned.

When the in-position sensor is triggered, the carrier 63 moves into position along the load-bearing belt line 13, and the load-bearing plate 12 moves to the bottom of the code reader 7. The base plate 14 is lifted to drive the carrier 63 to separate from the load-bearing belt line 13, and the code reader 7 recognizes the QR code on the circuit board 6.
